Poland's unemployment rate in June likely declined to 12.1% from 12.5% in May, PM Donald Tusk said on Wednesday in parliament citing a figure which shortly appeared on the Labor Ministry's website.

"June unemployment data will likely show unemployment rate of 12.1%," PM Donald Tusk said during a parliamentary debate.

The number of registered jobless amounted to 1.91 million and was the lowest since 2012, the ministry said on its website.

Nearly 71,900 persons were crossed off the register in June, but the unemployment rate decrease was also caused by the fact that fewer people came looking for jobs, Labor Minister Wladyslaw Kosiniak-Kamysz said as cited in the statement.

The number of vacancies reported by employers in June rose by over 10% year on year, he also said.
